Application filedj ebruary s, 1924. Serial No. 693304} 1 My invention relates to-machinery and particularly to thattype known as .a pipe or bolt threading machine. {A simple, portable,

inexpensive, efficientpipethreading machine has long been sou'ghtfby tradesmenwho the course, of theirbusiness; require large quantities of pipe to be threaded, ,The. principal obiect of my invention is to supply a machine answering vall. the requirementsof such demands andcontaining many features and improvements highly desirableand useful' inthe filtfjlo which they pertain.

One of my objects is to provide a machine of the character described which is light in.

weight, readily demountable and easy of operation, and which will permit the ready portability thereof, by the user, to one ob or another where it may be useful.

Another object is the provision of a new inexpensive and efficient type of ways upon which the head'of the machine travels.

Many other objects and advantages in details of construction and operation will be apparent as the description proceeds, reference being had to the accompanying drawings wherein like reference numerals indlcate like parts.

V Figure 1 is a side view of my improved machine, completely assembled and ready for operation.

Figure 2 is a perspective of the assembled machine showing the back and the side opposite that shown in Fig. 1.

Figure 8 is an exploded side view of a part of the machine showing the demountability of the ways and bed and the controlling lever for'the belt tensioning device.

' The base of my machine is indicated generally by the reference numeral 1 and as shown, is cut away around its sides as at 2, 3, 4, 5, 6 and 7, (Figs. 1 and 2) in order to. both lighten the machine in weightand to permit ready access to the parts and elements contained within the base. Abed 8 is removably mounted on the front of the base in a manner to be described. The upper end 9 of the base 1 is constructed to contain the driving mechanism,'and is enclosed by a removable cap or dome 10 secured inplace by means of screws 11. r

A chuck 12 is mounted at the top of the base 1 and is provided at the rear with the usual centering and steadying element controlled by the hand Wheel 13. This chuck;

course adapted t6 receive rotate a tion of pipe-or other element to. be threaded, indicated; in? Fig. llfat 14 l v Extending thru the base w was "of parallel openings 15 (see Figs. 2 and 3) in which are removably mounted" pair. of tubes or rods 16 constituting theway's fof the machine. Suitablebearings' 17 are pro- Qvided on the front of the ;base'an d set screws '18 said bearingsgprovide ,me'ans for' securfing saidways'agztirist inovementi The ways 'lGWhen 'securedHnposition extend from a point flush with the rear "of-"the-ba'sel as shown in Fig. 2, thru said base and projectlng beyond the front-thereof to provide a support for the outer end of the bed 8 p and for the head and carriage indicated generally at 19. The bed is provided at its outer, end with anysuitable securing meansv as for instance screws orbolts 20, whereby the bed is supportedby the outer ends of the ways.

The carriage 19 isslidably supported on the ways 16 by means of bearings 21 resting on topof said ways.

It will be noted by reference to Figs. 1 and 3 that the bed 8 slopes downwardly from its outer end toward thebase. The

inner end of the bed 8 is provided with a' funnel or'chute arrangement 47 which fits within an enlarged portion 48 of the base and which when in position, lies directly over the oil reservoir 42. This member 47 accomplishes a two fold purpose, first in,

providing a support or'resting means for,

the inner end of the bed 8 on the base whereby the bed is securely held in place, and secondly, acts to deliver the used oil back into the reservoir where it is again pumped thru the machine. This end piece 47 of the bed is ofiset' or shouldered as at 49 inorder to catch any cuttings and prevent them from being fed into the oil reservoir. The lower end of the bed 8 is of course screened at 50 as an additional safeguard against this. The sloping bottom of the bed 8 permits the used oil to readily advance in the m. As was described, the

drain thru the screen and be delivered by head and carriage, the ways and the bed may be quickly removed from the base which greatly facilitates; its ease of transportation. a I

Inasmuch as the operation of the device is obvious from the foregoing description of the various parts, the same will not be repeated here. It Will'be apparent to those skilled in the art that many changes in details of construction and operation are possible without departing from the scope of the invention. I do not limit myself, therefore, to the. exact construction shown and, described, other than by the appended claims I claim 1, A threading machine comprising a base, apair of. parallel supports removably mounted insaid base and projecting therefr m a -headand carriage slidable on said 7 supports, anda bed beneath said head removably supported at one end by said supports and at the opposite end by said base.

2., A threading machine comprising a base, provided with a pair of parallel supports projecting therefrom, a head and carriage. slidable on said supports, a hollow boss on said base beneath said supports, a removable bed beneath said head'supported .at one end by said supports and at the opposite end by said hollow boss.

3'. A threading machine comprising a base provided with a pair of-p arallel sup ports projectingtherefrom, a head and carriage sli'dable on said supports, a hollow boss on said base beneath said supports, a

removable bed beneath said head supported at one end by said supports and at the opposite end by said hollow boss, said bed having a projecting trough receivable in said boss; v a or LESLIE S. HALL,
